- Abstract:
  A two-stage method for 137Cs concentrating from seawater has been developed and adopted using composite ferrocyanide sorbents CFS Ni-K and CFS Zn-K(F). The suggested approach showed high efficiency that gives the opportunity to assess 137Cs content in the seawater without using low-background detectors. The data on 137Cs content has been obtained for the Japan, Okhotsk, and Bering seas using the suggested strategy. [ABSTRACT FROM AUTHOR]
